Demonstrations reveal slow chemical wave propagation in a gel, suggesting a time-saving teaching method.

The aim is to demonstrate the propagation of a chemical wave in an aqueous gel system.
Initiated a chemical wave in a system with potassium iodide and starch
Poured sodium hypochlorite solution over the gel
Captured 240 photos every 20 seconds to document the process
A blue disk formed at the surface boundary and propagated slowly downwards
The video created from the photos serves as an efficient teaching tool

Petruševski et al. (2004) studied this question.
